This is not reproducible for me with swift-DEVELOPMENT-SNAPSHOT-2022-01-09-a-osx. I'm getting these error messages when trying to build the archive from attachments:

SwiftGLib/Sources/GLib/GLib-2.0-constants.swift:706:31: error: cannot find 'G_VA_COPY_AS_ARRAY' in scope
public let VA_COPY_AS_ARRAY = G_VA_COPY_AS_ARRAY // 1
^~~~~~~~~~~~~~~~~~

swift --version shows this with that snapshot:

Apple Swift version 5.6-dev (LLVM 7b20e61dd04138a, Swift 9438cf6)

The auto-generated Glib-2.0-*.swift files are for the corresponding x86_64 .gir files, so I would not expect them to work out of the box on arm64. I don't have an arm64 Mac, but this should be reproducible on an Intel Mac.

If you wanted to try and reproduce this on arm64, these would be the steps to take (but YMMV as glib and the generated files would most likely be different):

brew install glib gobject-introspection
cd SwiftGLib
./distclean.sh
./run-gir2swift.sh
swift build

Thanks, with these steps it builds successfully for me with both Xcode 13.2.1 and swift-DEVELOPMENT-SNAPSHOT-2022-01-09-a. The latest 5.6 snapshot from swift.org is unfortunately broken for me, not with SwiftGLib, but for any purposes with unrelated errors, so I couldn't try that.

I did some more digging and have attached a minimal example (VAListPointer.zip) that reproduces this. This builds fine for any Xcode versions of Swift (including 5.6 from the latest beta), but crashes with the latest snapshots for both trunk and 5.6 (i.e. swift-DEVELOPMENT-SNAPSHOT-2022-01-09-a and swift-5.6-DEVELOPMENT-SNAPSHOT-2022-01-11-a).

The problem goes away when I replace UnsafeMutablePointer<va_list> with CVaListPointer, but obviously neither should crash the compiler.

With swift-DEVELOPMENT-SNAPSHOT-2022-01-09-a for x86_64, i.e.

Apple Swift version 5.6-dev (LLVM 7b20e61dd04138a, Swift 9438cf6)
Target: x86_64-apple-macosx12.0

I get the following crash/backtrace for the VAListPointer package example:

$ swift build
